黑龙江省团结沟地区隐伏金矿体预测准则

The prognostic norms of blind gold orebody in TuanJieGou area,Heilongjiang Province

在严重植被覆盖区进行隐伏金矿体预测必须运用地质、地球化学、地球物理等综合信息。在团结沟地区应本着下列准则：斜长花岗斑岩与围岩的接触带、围岩蚀变明显及找矿标型矿物有利，Ａｕ、Ａｓ、Ｓｂ组合异常明显，磁异常呈现低缓局部正异常，大功率电法呈现高阻高极化，上述异常相吻合地段是预测隐伏金矿体最佳部位。

To make prognosis of blind gold orebody in heavy vegetation covering area must have synthetic informations including geological,geochemical,geophysical information etc.To make prognosis of it in TuanJieGou area must adhere to the following norms:A contact zone of country rock and plagioclaseporphyrite granite;Obvious alternation of country rock and typomorphic minerals for prospecting;Obvious anomalous distribution of elements Au,As,Sb;Presenting low and slow local positive anomaly of magnetic anomaly;Presenting high resistivity and polarizability in high power electromagnetic prospecting.The sectors of this area which coincide with the anomalies mentioned above are the best prognostic places of blind gold orebody.
